Citroen c3 III 2017 Ignition barrel antenna connection BSI

Post by rico_pl »

Hello,
I have following question : I have a keyless entry model where I had to replace all electronics due to flood.
Now I have a Ecu kit from a standard C3 (with key start). As I can not plug in the brown connector (antenna) the
key is obviously not recognized.
So my question is which connector and pins on the BSI can I use for the key antenna ? (2 pins)

The car has several antennas for the keyless entry.

I used an immo off ecu which ran fine for sometime but now seems broken, I donot want to use this ecu as it
might kill my "new" BSI (9819851280-01).

Thanks for any hints or solution.

BR,
Rico

The transponder aerial doesn’t have a direct connection to the BSI, it plugs into a dedicated socket on the com2000 unit which has a CAN connection to the BSI. Are the connections there for the ignition switch??
I don’t really know the keyless system well enough to know if this it a feasible conversation or not.
